Keith Urban and his wife Nicole Kidman visited a children's hospital this past Friday in Clayton, Australia and gave an impromptu concert to lift everyone's spirits.

In the video, Urban and his wife sing "Amazing Grace" at the Monash Children’s Hospital and midway through Urban's rendition, Kidman jumps in. It even looks like she saves Urban as he stumbles a bit with the song's words. The two look completely at home, supporting a good cause.
